Emotion, Experience, and Co-experience

This panel proposes a theoretical framework for experience design. One panelist's web-site also has summaries of other theoretical HCI contributions (their words, not mine).

Their framework posits that three dimensions of experience are:
1) the constant stream of experience that happens when we are conscious
2) narratives describing experience (and change the context and user as a result)
3) co-experience, when experiences are created with others.

They also break down user interactions into three types:
1) sub-conscious (or pre-attentive?)
2) cognitive, requiring attention and changing user and context as a result
3) narrative, in which a sequence of interactions is had with a product.

Is the point of this just to introduce a vocabulary?
